Inventor: INAGE TORU
IPC: F16C32/00
Filed: 1988-10-11
Abstract: PURPOSE:To obtain a dynamic pressure fluid bearing device of high performance by tightly closing up a gas having smaller density than air in a housing. CONSTITUTION:Pipes 24, 25 provided with valves 22, 23 are respectively arranged on the upper and lower part of a side wall in the housing 21 of a dynamic pressure gas radial bearing device 19.
